FIELD OF THE INVENTION

The present invention relates to certain substituted pyridine and pyrimidine derivatives, to compositions comprising them, and to methods for their use as inhibitors of HCV and in treating or preventing viral infections or virus-related disorders.

BACKGROUND OF THE INVENTION

HCV is a (+)-sense single-stranded RNA virus that has been implicated as the major causative agent in non-A, non-B hepatitis (NANBH). NANBH is distinguished from other types of viral-induced liver disease, such as hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis delta virus (HDV), as well as from other forms of liver disease such as alcoholism and primary biliary cirrhosis.

Hepatitis C virus is a member of the hepacivirus genus in the family Flaviviridae. It is the major causative agent of non-A, non-B viral hepatitis and is the major cause of transfusion-associated hepatitis and accounts for a significant proportion of hepatitis cases worldwide. Although acute HCV infection is often asymptomatic, nearly 80% of cases resolve to chronic hepatitis. About 60% of patients develop liver disease with various clinical outcomes ranging from an asymptomatic carrier state to chronic active hepatitis and liver cirrhosis (occurring in about 20% of patients), which is strongly associated with the development of hepatocellular carcinoma (occurring in about 1-5% of patients). The World Health Organization estimates that 170 million people are chronically infected with HCV, with an estimated 4 million living in the United States.

HCV has been implicated in cirrhosis of the liver and in induction of hepatocellular carcinoma. The prognosis for patients suffering from HCV infection remains poor as HCV infection is more difficult to treat than other forms of hepatitis. Current data indicate a four-year survival rate of below 50% for patients suffering from cirrhosis and a five-year survival rate of below 30% for patients diagnosed with localized resectable hepatocellular carcinoma. Patients diagnosed with localized unresectable hepatocellular carcinoma fare even worse, having a five-year survival rate of less than 1%.

Replication of HCV is thought to occur in membrane-associated replication complexes. Within these, the genomic plus-strand RNA is transcribed into minus-strand RNA, which in turn can be used as a template for synthesis of progeny genomic plus-strands. At least two viral enzymes appear to be involved in this reaction: the NS3 helicase/NTPase, and the NS5B RNA-dependent RNA polymerase. While the role of NS3 in RNA replication is less clear, NS5B is the key enzyme responsible for synthesis of progeny RNA strands. Using recombinant baculoviruses to express NS5B in insect cells and a synthetic nonviral RNA as a substrate, two enzymatic activities have been identified as being associated with it: a primer-dependent RdRp and a terminal transferase (TNTase) activity. It was subsequently confirmed and further characterized through the use of the HCV RNA genome as a substrate. Other studies have shown that NS5B with a C-terminal 21 amino-acid truncation expressed in Escherichia coli is also active for in vitro RNA synthesis. On certain RNA templates, NS5B has been shown to catalyze RNA synthesis via a de novo initiation mechanism, which has been postulated to be the mode of viral replication in vivo. Templates with single-stranded 3′ termini, especially those containing a 3′-terminal cytidylate moiety, have been found to direct de novo synthesis efficiently. There has also been evidence for NS5B to utilize di- or tri-nucleotides as short primers to initiate replication.

Particular therapies for HCV infection include α-interferon monotherapy and combination therapy comprising α-interferon and ribavirin. These therapies have been shown to be effective in some patients with chronic HCV infection. The use of antisense oligonucleotides for treatment of HCV infection has also been proposed as has the use of free bile acids, such as ursodeoxycholic acid and chenodeoxycholic acid, and conjugated bile acids, such as tauroursodeoxycholic acid. Phosphonoformic acid esters have also been proposed as potentially for the treatment of various viral infections including HCV. Vaccine development, however, has been hampered by the high degree of viral strain heterogeneity and immune evasion and the lack of protection against reinfection, even with the same inoculum.

NS5B, the RNA-dependent RNA polymerase, is an important and attractive target for small-molecule inhibitors. Studies with pestiviruses have shown that the small molecule compound VP32947 (3-[((2-dipropylamino)ethyl)thio]-5H-1,2,4-triazino[5,6-b]indole) is a potent inhibitor of pestivirus replication and most likely inhibits the NS5B enzyme since resistant strains are mutated in this gene. Inhibition of RdRp activity by (−)β-L-2′,3′-dideoxy-3′-thiacytidine 5′-triphosphate (3TC; lamivudine triphosphate) and phosphonoacetic acid also has been observed.

In this specification, where there are multiple oxygen and/or sulfur atoms in a ring system, there cannot be any adjacent oxygen and/or sulfur present in said ring system. It is noted that the carbon atoms for compounds of the invention may be replaced with 1 to 3 silicon atoms so long as all valency requirements are satisfied. As well known in the art, a bond drawn from a particular atom wherein no moiety is depicted at the terminal end of the bond indicates a methyl group bound through that bond to the atom, unless stated otherwise. For example:

The term “purified”, “in purified form” or “in isolated and purified form” for a compound refers to the physical state of said compound after being isolated from a synthetic process (e.g. from a reaction mixture), or natural source or combination thereof. Thus, the term “purified”, “in purified form” or “in isolated and purified form” for a compound refers to the physical state of said compound after being obtained from a purification process or processes described herein or well known to the skilled artisan (e.g., chromatography, recrystallization and the like), in sufficient purity to be characterizable by standard analytical techniques described herein or well known to the skilled artisan.

It should also be noted that any carbon (or other atom or heteroatom) with unsatisfied valences in the text, schemes, examples and Tables herein is assumed to have the sufficient number of hydrogen atom(s) to satisfy the valences.

When a functional group in a compound is termed “protected”, this means that the group is in modified form to preclude undesired side reactions at the protected site when the compound is subjected to a reaction. Suitable protecting groups will be recognized by those with ordinary skill in the art as well as by reference to standard textbooks such as, for example, T. W. Greene et al, Protective Groups in Organic Synthesis (1991), Wiley, New York.

As used herein, the term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combination of the specified ingredients in the specified amounts.

Prodrugs and solvates of the compounds of the invention are also contemplated herein. A discussion of prodrugs is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems (1987) 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, (1987) Edward B. Roche, ed., American Pharmaceutical Association and Pergamon Press. The term “prodrug” means a compound (e.g., a drug precursor) that is transformed in vivo to yield a compound of the invention or a pharmaceutically acceptable salt, hydrate or solvate of the compound. The transformation may occur by various mechanisms (e.g., by metabolic or chemical processes), such as, for example, through hydrolysis in blood. A discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.

For example, if a compound of the invention or a pharmaceutically acceptable salt, hydrate or solvate of the compound contains a carboxylic acid functional group, a prodrug can comprise an ester formed by the replacement of the hydrogen atom of the acid group with a group such as, for example, (C₁-C₈)alkyl, (C₂-C₁₂)alkanoyloxymethyl, 1-(alkanoyloxy)ethyl having from 4 to 9 carbon atoms, 1-methyl-1-(alkanoyloxy)-ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N—(C₁-C₂)alkylamino(C₂-C₃)alkyl (such as β-dimethylaminoethyl), carbamoyl-(C₁-C₂)alkyl, N,N-di(C₁-C₂)alkylcarbamoyl-(C1-C2)alkyl and piperidino-, pyrrolidino- or morpholino(C₂-C₃)alkyl, and the like.

Similarly, if a compound of the invention contains an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a group such as, for example, (C₁-C₆)alkanoyloxymethyl, 1-((C₁-C₆)alkanoyloxy)ethyl, 1-methyl-1-((C₁-C₆)alkanoyloxy)ethyl, (C₁-C₆)alkoxycarbonyloxymethyl, N—(C₁-C₆)alkoxycarbonylaminomethyl, succinoyl, (C₁-C₆)alkanoyl, α-amino(C₁-C₄)alkanyl, arylacyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl, where each α-aminoacyl group is independently selected from the naturally occurring L-amino acids, P(O)(OH)₂, —P(O)(O(C₁-C₆)alkyl)₂ or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate), and the like.

If a compound of the invention incorporates an amine functional group, a prodrug can be formed by the replacement of a hydrogen atom in the amine group with a group such as, for example, R-carbonyl, RO-carbonyl, NRR′-carbonyl where R and R′ are each independently (C₁-C₁₀)alkyl, (C₃-C₇)cycloalkyl, benzyl, or R-carbonyl is a natural α-aminoacyl or natural α-aminoacyl, —C(OH)C(O)OY¹ wherein Y¹ is H, (C₁-C₆)alkyl or benzyl, —C(OY²)Y³ wherein Y² is (C₁-C₄)alkyl and Y³ is (C₁-C₆)alkyl, carboxy(C₁-C₆)alkyl, amino(C₁-C₄)alkyl or mono-N- or di-N,N—(C₁-C₆)alkylaminoalkyl, —C(Y⁴)Y⁵ wherein Y⁴ is H or methyl and Y⁵ is mono-N- or di-N,N—(C₁-C₆)alkylamino morpholino, piperidin-1-yl or pyrrolidin-1-yl, and the like.

One or more compounds of the invention may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and it is intended that the invention embrace both solvated and unsolvated forms. “Solvate” means a physical association of a compound of this invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. “Solvate” encompasses both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like. “Hydrate” is a solvate wherein the solvent molecule is H₂O.

One or more compounds of the invention may optionally be converted to a solvate. Preparation of solvates is generally known. Thus, for example, M. Caira et al, J. Pharmaceutical Sci., 93(3), 601-611 (2004) describe the preparation of the solvates of the antifungal fluconazole in ethyl acetate as well as from water. Similar preparations of solvates, hemisolvate, hydrates and the like are described by E. C. van Tonder et al, AAPS PharmSciTech., 5(1), article 12 (2004); and A. L. Bingham et al, Chem. Commun., 603-604 (2001). A typical, non-limiting, process involves dissolving the inventive compound in desired amounts of the desired solvent (organic or water or mixtures thereof) at a higher than ambient temperature, and cooling the solution at a rate sufficient to form crystals which are then isolated by standard methods. Analytical techniques such as, for example IR spectroscopy, show the presence of the solvent (or water) in the crystals as a solvate (or hydrate).

“Effective amount” or “therapeutically effective amount” is meant to describe an amount of compound or a composition of the present invention effective in inhibiting the above-noted diseases and thus producing the desired therapeutic, ameliorative, inhibitory or preventative effect.

The compounds of the invention can form salts which are also within the scope of this invention. Reference to a compound of the invention herein is understood to include reference to salts thereof, unless otherwise indicated. The term “salt(s)”, as employed herein, denotes acidic salts formed with inorganic and/or organic acids, as well as basic salts formed with inorganic and/or organic bases. In addition, when a compound of the invention contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions (“inner salts”) may be formed and are included within the term “salt(s)” as used herein. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the invention may be formed, for example, by reacting a compound of the invention with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization.

Exemplary acid addition salts include acetates, ascorbates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, fumarates, hydrochlorides, hydrobromides, hydroiodides, lactates, maleates, methanesulfonates, naphthalenesulfonates, nitrates, oxalates, phosphates, propionates, salicylates, succinates, sulfates, tartarates, thiocyanates, toluenesulfonates (also known as tosylates) and the like. Additionally, acids which are generally considered suitable for the formation of pharmaceutically useful salts from basic pharmaceutical compounds are discussed, for example, by P. Stahl et al, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use. (2002) Zurich: Wiley-VCH; S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(1) 1-19; P. Gould, International J. of Pharmaceutics (1986) 33 201-217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (Food & Drug Administration, Washington, D.C. on their website). These disclosures are incorporated herein by reference thereto.

Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases (for example, organic amines) such as dicyclohexylamines, t-butyl amines, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g. methyl, ethyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, and dibutyl sulfates), long chain halides (e.g. decyl, lauryl, and stearyl chlorides, bromides and iodides), aralkyl halides (e.g. benzyl and phenethyl bromides), and others.

All such acid salts and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention.

Pharmaceutically acceptable esters of the present compounds include the following groups: (1) carboxylic acid esters obtained by esterification of the hydroxy groups, in which the non-carbonyl moiety of the carboxylic acid portion of the ester grouping is selected from straight or branched chain alkyl (for example, acetyl, n-propyl, t-butyl, or n-butyl), alkoxyalkyl (for example, methoxymethyl), aralkyl (for example, benzyl), aryloxyalkyl (for example, phenoxymethyl), aryl (for example, phenyl optionally substituted with, for example, halogen, C₁₋₄alkyl, or C₁₋₄alkoxy or amino); (2) sulfonate esters, such as alkyl- or aralkylsulfonyl (for example, methanesulfonyl); (3) amino acid esters (for example, L-valyl or L-isoleucyl); (4) phosphonate esters and (5) mono-, di- or triphosphate esters. The phosphate esters may be further esterified by, for example, a C₁₋₂₀ alcohol or reactive derivative thereof, or by a 2,3-di(C₆₋₂₄)acyl glycerol.

Compounds of the invention, and salts, solvates, esters and prodrugs thereof, may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present invention.

The compounds of the invention may contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the compounds of the invention as well as mixtures thereof, including racemic mixtures, form part of the present invention. In addition, the present invention embraces all geometric and positional isomers. For example, if a compound of the invention incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention.

Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of the invention may be atropisomers (e.g., substituted biaryls) and are considered as part of this invention. Enantiomers can also be separated by use of chiral HPLC column.

It is also possible that the compounds of the invention may exist in different tautomeric forms, and all such forms are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention.

All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates, esters and prodrugs of the compounds as well as the salts, solvates and esters of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this invention, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). (For example, if a compound of the invention incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention).

Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms “salt”, “solvate”, “ester”, “prodrug” and the like, is intended to equally apply to the salt, solvate, ester and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds.

The present invention also embraces isotopically-labelled compounds of the present invention which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively.

Certain isotopically-labelled compounds of the invention (e.g., those labeled with ³H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ¹⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labelled compounds of the invention can generally be prepared by following procedures analogous to those disclosed in the Schemes and/or in the Examples hereinbelow, by substituting an appropriate isotopically labelled reagent for a non-isotopically labelled reagent.

Polymorphic forms of the compounds of the invention, and of the salts, solvates, esters and prodrugs of the compounds of the invention, are intended to be included in the present invention.

Suitable doses for administering compounds of the invention to patients may readily be determined by those skilled in the art, e.g., by an attending physician, pharmacist, or other skilled worker, and may vary according to patient health, age, weight, frequency of administration, use with other active ingredients, and/or indication for which the compounds are administered. Doses may range from about 0.001 to 500 mg/kg of body weight/day of the compound of the invention. In one embodiment, the dosage is from about 0.01 to about 25 mg/kg of body weight/day of a compound of the invention, or a pharmaceutically acceptable salt or solvate of said compound. In another embodiment, the quantity of active compound in a unit dose of preparation may be varied or adjusted from about 1 mg to about 100 mg, preferably from about 1 mg to about 50 mg, more preferably from about 1 mg to about 25 mg, according to the particular application. In another embodiment, a typical recommended daily dosage regimen for oral administration can range from about 1 mg/day to about 500 mg/day, preferably 1 mg/day to 200 mg/day, in two to four divided doses.

As discussed above, the amount and frequency of administration of the compounds of the invention and/or the pharmaceutically acceptable salts thereof will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated.

When used in combination with one or more additional therapeutic agents, the compounds of this invention may be administered together or sequentially. When administered sequentially, compounds of the invention may be administered before or after the one or more additional therapeutic agents, as determined by those skilled in the art or patient preference.

If formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described herein and the other pharmaceutically active agent or treatment within its dosage range.

Accordingly, in an aspect, this invention includes combinations comprising an amount of at least one compound of the invention, or a pharmaceutically acceptable salt, solvate, ester or prodrug thereof, and an effective amount of one or more additional agents described above.

The pharmacological properties of the compounds of this invention may be confirmed by a number of pharmacological assays. Certain assays are exemplified elsewhere in this document.

For preparing pharmaceutical compositions from the compounds described by this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may be comprised of from about 5 to about 95 percent active ingredient. Suitable solid carriers are known in the art, e.g., magnesium carbonate, magnesium stearate, talc, sugar or lactose. Tablets, powders, cachets and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and methods of manufacture for various compositions may be found in A. Gennaro (ed.), Remington's Pharmaceutical Sciences, 18^(th) Edition, (1990), Mack Publishing Co., Easton, Pa.

Liquid form preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injection or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.

Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g. nitrogen.

Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.

The compounds of the invention may also be deliverable transdermally. The transdermal compositions can take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.

The compounds of this invention may also be delivered subcutaneously.

In one embodiment, the compound is administered orally.

In some embodiments, it may be advantageous for the pharmaceutical preparation comprising one or more compounds of the invention be prepared in a unit dosage form. In such forms, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.

Example 5 Procedure A-1

To a stirred mixture of 2-amino-4,6-dichloropyrimidine (1, X, Y=N, Z=Cl, 5.0 g, 30.5 mmol) in glacial acetic acid (120 mL) was added dropwise a solution of ICl (5.01 mL, 100 mmol) in glacial acetic acid (120 mL). After 5 h, the mixture was filtered, and the collected solids were washed with glacial acetic acid and then azeotroped with toluene (2×), giving 2.78 g of 2 as a white solid. After 7 days, more solid was visible in the filtrate, and thus, it was again filtered, the collected solids washed with glacial acetic acid and azeotroped with toluene (2×), giving another 4.22 g of 2, with TLC and MS data that matched the first batch.

Example 5 (1R,2S,3R,5R)-3[(2-amino-6-chloro-5-phenyl-4-pyrimidinyl)amino]-5-hydroxymethyl)-1,2-cyclopentanol

To a stirring solution of compound 3 (X, Y=N, Z=Cl, R¹=NH₂, R², R³, R⁴, R⁷, R⁸=H, R⁵, R⁶=OH, R⁹=CH₂OH, 0.1 g; 0.25 mmol) (under Ar at room temperature) and phenylboronic acid (0.04 g; 0.3 mmol) in anhydrous DMF (5.0 mL) was added anhydrous K₂CO₃ (0.17 g; 1.25 mmol). After 5.0 min, tetrakis(triphenylphosphine)-palladium (0) (0.014 g; 0.012 mmol) was added. The reaction vessel (RB flask) was then covered with aluminum foil and stiffed at 90° C. for 24 h. Then, the reaction mixture was cooled to room temperature (22° C.), and the solvent was removed in vacuo and then co-evaporated with MeOH. The obtained brown residue was purified by column chromatography, eluting with 94:6 CHCl₃/MeOH (V/V) (Fisher), giving the pure product 5 (Structure 4, General Method I, R=phenyl, X, Y=N, Z=Cl, R¹=NH₂, R², R³, R⁴, R⁷, R⁸=H, R⁵, R⁶=OH, R⁹=CH₂OH) as an off-white solid (0.045 g).

Example 9 Procedure A-2

To a degassed solution of 3 (synthesis previously described, X, Y=N, Z=Cl, R¹=NH₂, R², R³, R⁴, R⁷, R⁸=H, R⁵, R⁶=OH, R⁹=CH₂OH, 5.0 g, 12.5 mmol) in DMF (50 ml) was added (with protection from light) triethylamine (7.0 mL, 50 mmol) dropwise over 10 min, followed by CuI (952 mg, 5.0 mmol) and then tetrakis(triphenylphosphine)palladium (2.9 g, 2.5 mmol). After degassing with Ar for 10 min, the addition of TMS acetylene (5.3 mL, 37.5 mmol) was followed by sealing the reaction vessel with a rubber septum. Then, while still protecting the sealed flask from light, the reaction mixture was heated in an oil bath at 55° C. for 18 h. After concentrating, the methanol extract was filtered, and the filtrate concentrated onto silica. Chromatography on silica (eluting gradient of CHCl₃/MeOH (95/5→90/10) gave 2.62 g of a brown foam that contained triethylamine salts. A second chromatography (eluting with EtOAc/MeOH, 95/5) gave 2.55 g of 3a (X, Y=N, Z=Cl, R¹=NH₂, R², R³, R⁴, R⁷, R⁸=H, R⁵, R⁶=OH, R⁹=CH₂OH) as a reddish brown solid. (Even after the 2 chromatographic isolations, the obtained 3a still contained impurities, by TLC, that was used as is in the next reaction.)

The reaction was then heated on a 50° oil bath for ˜20 h. The reaction mixture was concentrated under vacuum and then partitioned with methylene chloride and water. The organic extract was washed with water, dried over Na₂SO₄, and concentrated. The crude product was chromatographed on silica gel eluting with chloroform/methanol (grad. 0 to 2% MeOH) to giving 31f (10.47 g, 93.6%) as a dark, highly colored foam or viscous glass.

Step 4: To a stirred methylene chloride (40 mL) solution of 31f (1.0 g, 2.4 mmol), cooled in an ice/water bath, was added mCPBA (655 mg, 2.8 mmol) in one aliquot. After ˜1 h saturated aq. Na₂S₂O₃ was then added, and the mixture was diluted with methylene chloride and water. The organic extract was washed with water, saturated brine, dried over Na₂SO₄, and concentrated. The residue was chromatographed on silica gel eluting with chloroform/methanol (grd. 0 to 5% MeOH). Sulfoxide 31g (747 mg, 71.1%) was isolated as a mixture of diastereomers (by NMR). A small amount (146 mg) of the sulfone corresponding to 31g was also isolated.

Step 5: To a solution of sulfoxide 31g (747 mg, 1.71 mmol) in CH₃CN under argon with stirring was added Et₄NF.2H₂O (106 mg, 0.57 mmol). The reaction was allowed to stir overnight then chromatographed on silica gel eluting with chloroform/methanol (grad. 0 to 4% MeOH).

After 10 min stirring, (Ph₃P)₄Pd (58 mg, 0.05 mmol) was added, and after another ˜2 min of argon bubbling, the reaction tube was capped and microwaved at 300 W at 90° C. for 10 min. The reaction mixture was then concentrated, taken up in MeOH, and filtered. The filtrate was chromatographed on silica gel eluting with chloroform/methanol (grad. 0 to 5% MeOH). The desired product 31i was isolated as a yellow foam (232 mg, 89.8% yield).

Step 7: To a solution of sulfoxide 31i (100 mg, 0.194 mmol) in acetonitrile (5 mL) was added methoxyethylamine (0.17 ml, 1.94 mmol). The resulting solution was refluxed overnight. After cooling to room temperature, a solid formed which was isolated by filtration, collected, washed with acetonitrile, and then dried under vacuum.

Then, solid I₂ (112.0 g (0.44 mol) was added in one portion, and the resulting suspension was left to warm to room temp overnight with stirring. The suspension was then treated with a concentrated sodium thiosulfate solution (˜60 mL), and then conc. HCl (˜115 ml) was added dropwise with via an addition funnel at a rate that avoided clumping. (The addition of a little EtOAc helped to separate any clumps that formed. The pH of the resulting suspension is about 2-3 by pH paper.) The resulting mixture was then extracted with EtOAc (3×150 mL) and the combined organic layers washed with brine (1×400 mL), dried (Na₂SO₄), filtered, and concentrated to dryness.

A mixture of 3-pentanol (1.5 mL, 0.013 mol) and 4 Å molecular sieves (˜0.7 g, crushed and activated) in THF (50 mL) was stirred for ˜10 min at room temp under argon). NaH was then added in portions over ˜5 min, and the mixture was allowed to stir until H2 evolution ceased (˜5 min). To this mixture was added 48B (2.5 g, 6.9 mmol) followed by CuBr (0.2 g, 0.0013 mol), and the mixture was placed in an oil bath maintained at 85-90° C. After 2 h, TLC showed that the starting material was essentially consumed, and the mixture was filtered through Celite and washed with a minimal amount of CH₂Cl₂. The solvent was then removed in vacuo, and the residue was partitioned between EtOAc and ˜0.5 M HCl (15 mL each). The organic layer was separated and washed with sodium thiosulfate (1×15 mL), brine (1×15 mL) and concentrated to dryness.

After ˜10 min, TBDPS-Cl was added dropwise by syringe to the stiffed mixture over ˜10 min. The reaction mixture was stiffed at RT for 20.5 h and then filtered. The collected solid was washed with CH₂Cl₂, the filtrate plus washes were diluted with more CH₂Cl₂ and then transferred to a separatory funnel. This solution was washed with cold saturated NaHCO₃ (pH˜8), water, and brine. The organic layer was then dried over MgSO₄ and evaporated to an off-white foam (4.45 g). Flash column chromatography eluting with a 0-90% gradient of cyclohexane/CHCl₃ gave the desired intermediate 4905B in 76% yield (2.78 g) along with some starting material (57.4 mg) and the corresponding 2′-OH (3′-O-protected) product (477 mg, 13%).

To an argon-flushed pressure tube (˜120 mL capacity) was added DTBMP (7.42 g, 35.4 mmol) and 4905B (1.78 g, 2.36 mmol). CH₂Cl₂ (18 mL) was then added, the mixture was stiffed, and methyl triflate (3.4 mL, 29.5 mmol) was added by syringe. The tube was again flushed with argon, tightly sealed, and placed into a preheated 90° C. oil bath for 10 h, then allowed to cool to RT overnight. The reaction mixture was then poured into cold saturated NaHCO₃ (˜125 mL) with vigorous stirring. This mixture was stirred at RT for 1 h, EtOAc (˜150 mL) was added, and after ˜5 min more stirring, it was transferred to a separatory funnel. The organic layer was isolated and washed with water and brine. Drying with MgSO₄ followed by evaporation gave an off-white slurry (8.83 g after drying). Flash column chromatography, eluting with a gradient of 0-10% EtOAc/hexane gave 4905C (1.63 g, 90%).

Intermediate 4905C (2.55 g, 3.32 mmol) was added to hot EtOH (50 mL), and the resulting cloudy solution was treated in one portion with hydrazine hydrate (2.47 mL, 49.9 mmol). The reaction flask was then equipped with a reflux condenser and the mixture heated in a preheated 90° C. oil bath. After 15 min, a white solid began forming. After 5 h, the reaction mixture was a thick slurry. The reaction mixture was removed from the oil bath, and the mixture stiffed at RT overnight. The white solid was then collected, washed with EtOH, and the EtOH filtrate evaporated to a white solid (2.22 g). Flash column chromatography of this solid eluting with CHCl₃ and then 99:1 CHCl₃/7N NH₃ in MeOH then gave 2.3 g of 4905D.

Conversion of 4905D to 4905E followed analogous procedures presented earlier.

Solid Et₄NF (50 mg, 0.333 mmol) was added in one portion to a solution of 4905E in MeCN in a 15 mL pressure reaction tube. The tightly sealed tube was placed into a preheated 85° C. oil bath for 3 h. The reaction mixture was evaporated to a yellow semisolid 118.9 mg which was then purified by prep TLC (Analtech GF plated) developed 4 times in 9:1 CHCl₃/MeOH+1% NH₄OH. The product-containing bands from the multiple plates were extracted with MeOH containing a few drops of NH₄OH. The washes were evaporated to a white solid which was then added to boiling MeCN, and a few drops of water added to clarify. When the solution was allowed to slowly cool to RT, little material came out of solution, and so the mixture was concentrated to ˜5 mL and then refrigerated overnight. The resulting white solid was collected, washed with cold MeCN, dried in vacuo to give 4905 (25.6 mg, 77%).

Preparation of 4923:

Compound 4923A (0.5 g, 1.65 mmol) was added to MeCN (5 mL) and treated with TBTU (0.6 g, 1.86 mmol) at RT with stirring under argon. Morpholine (0.16 mL, 1.8 mmol) and DIPEA (0.32 mL) in MeCN (5 mL) was added, and the reaction mixture was stiffed at RT overnight. The reaction mixture was then concentrated to dryness, preadsorbed onto silica, and purified by column chromatography, eluting with 0-30% EtOAc/CHCl₃, giving 4923B (0.456 g).

BOC-protected 4923B (2.3 g, 6.21 mmol) was added slowly to TFA with stirring at RT. After 1.5 h, the reaction mixture was concentrated to dryness and co-evaporated with toluene (2×25 mL) to give 4923C, which was used without further purification.

Conversion of 4923C to provide 4923D, followed by introduction of the 5-heterocycle to afford 4923E was performed by the same procedures described previously.

Replacement of the 2-SMe of 4923E with the α-methyl-cyclopropylmethylamine followed by removal of the isopropylidine protecting group to give target compound 4923 was performed by the same procedures described previously.

Preparation of 4954:

To a solution of 4954A (860 mg, 1.71 mmol) in anhydrous CH₂Cl₂ at 0-5° C. was added dropwise (syringe) 50% Deoxo-Fluor in THF (1.46 mL, 3.43 mmol) over 14 min. The yellow solution was stirred at 0-5° C., and after 1.5 h, only a trace of Im-23 was present (by TLC). After 2 h at 0-5° C., cold saturated NaHCO₃ was added, and then solid NaHCO₃ was added in small portions until bubbling ceased. The solution as diluted with CH₂Cl₂, stirring at 5° C. was continued for ˜0.5 h. The mixture was then transferred to a separatory funnel, shaken and the layers were separated. The aqueous layer was extracted with portions of CH₂Cl₂ until the organic layer remained essentially colorless. The organic layers were combined, washed with water (×2) dried (MgSO₄), evaporated to a light orange solid (840 mg). Chromatographic purification of this solid using an ISCO chromatography system (ISCO Gold cartridge) eluting with a 0-20% acetone/cyclohexane gradient gave 4954B (79 mg).

Conversion of 4954B to 4954C followed analogous procedures presented earlier. Aqueous 1N HCl was added in one portion at RT to a suspension of 4954C (87.4 mg, 0.165 mmol) in MeOH resulting in complete dissolution. The reaction mixture was stirred at RT for 33 h, and after TLC showed the reaction was complete, the solution was evaporated to a small volume. Since the solution was still acidic, it was diluted with MeOH, stirred for 3.5 h, and then evaporated to dryness. The residue was coevaporated 2× with MeOH to give a pale yellow solid (468 mg). Flash column chromatography on silica gel eluting with a gradient of 0-5% MeOH/CHCl₃ gave 4954 (74.8 mg).

Preparation of Amine Intermediates Required for Examples 5226-5235:

Step 1.

A reaction tube was charged with a solution of (S)-2-(trifluoromethyl)oxirane, 5233Aa (1.12 g, 10.0 mmol) in THF (50 mL) and water (10 mL). Sodium azide (2.0 eq, 1.30 g) and ammonium chloride (2.0 eq, 1.07 g) were added and the tube was sealed. The reaction mixture was heated (oil bath at 65° C.) for 3 h. The mixture was treated with aqueous 2 N NaOH (20 mL) and the product was taken into ether (150 mL). Upon separation, the organic layer was washed with brine (50 mL), dried over magnesium sulfate, filtered and concentrated to almost dryness in rotavap (no heating in water bath). The residue was dissolved in methanol (50 mL) and treated with a catalytic amount of 10% palladium on carbon (tip of spatula). The mixture was hydrogenated at room temperature (balloon pressure) for 2 h. The mixture was diluted with methanol (100 mL) and the solids were removed by filtration. The filtrate was concentrated in rotavap to give the crude product 5233Ab (700 g, 54%) as a white powder.

Step 2.

The amino-alcohol 5233Ab (700 mg, 5.42 mmol) was dissolved in THF (10 mL) and treated with a solution of Boc anhydride (1.0 eq, 1.18 g) in THF (15 mL) and Hunig's base (1.0 eq, 0.943 mL, d 0.742). The reaction mixture was stirred for 3 h. TLC (20% ethyl acetate in hexanes) showed a new spot. The mixture was diluted with ethyl acetate (80 mL) and washed with aqueous 1 M HCl (15 mL) and brine (15 mL), dried over magnesium sulfate, filtered and concentrated in rotavap. The residue was adsorbed on silica gel and purified on a Redisep® gold cap (40 g) silica gel column (gradient: 0 to 40% ethyl acetate in hexanes) to give the product 5233Ac (1.25 g, 100%) as a colorless oil.

Step 3.

The N-Boc-protected amino-alcohol 5233Ac (620 mg, 2.705 mmol) was suspended in toluene (5 mL) and enough THF was added to obtain a homogeneous solution (aprox 1 mL). The resulting solution was treated with iodoethane (3.0 eq, 0.650 mL, d 1.950). The mixture was placed in an ice-water bath and treated with aqueous 50% NaOH (2.7 mL) and tetrabutylammonium hydrogen sulfate (0.2 eq, 183 mg). The cooling bath was removed the slurry was stirred for 24 h at 45° C. TLC (20% ethyl acetate in hexanes) showed about 80% conversion. The mixture was diluted with ethyl acetate (25 mL) and water (5 mL) and layers were separated. The aq layer was back-extracted with ethyl acetate (2×25 mL) and the combined organic layers were washed with brine (5 mL), dried over magnesium sulfate, filtered and concentrated in rotavap. The residue was purified on a Redisep® (40 g) silica gel column (gradient: 0 to 25% ethyl acetate in hexanes) to give the product 5233Ad (365 mg, 53%) as a white powder. Unreacted starting material was also recovered (247 mg, 40%).

Step 4.

The N-Boc protected amine 5233Ad (345 mgm 1.341 mmol) was dissolved in 4 M HCl in dioxane. The mixture was stirred for 1 h and TLC showed a complete reaction. The mixture was concentrated to dryness in rotavap to give the crude product 5233A (ca 100%, 258 mg) as a white powder. No further purification was carried out.

The amine intermediates 5226A and 5230A were prepared using a similar procedure.

ASSAYS

Cell-Based HCV Replicon Assay

To measure cell-based anti-HCV activity of the compounds of the present invention, replicon cells were seeded at 5000 cells/well in 96-well collagen I-coated Nunc plates in the presence of the compound of the invention. Various concentrations of a compound of the invention, typically in 10 serial 2-fold dilutions, were added to the assay mixture, the starting concentration of the compound ranging from 25 μM to 1 μM. The final concentration of DMSO was 0.5%, fetal bovine serum was 10%, in the assay media. Cells were harvested on day 3 by the addition of 1× cell lysis buffer (Ambion cat #8721). The replicon RNA level was measured using real time PCR (Taqman assay). The amplicon was located in 5B. The PCR primers were: 5B.2F, ATGGACAGGCGCCCTGA; 5B.2R, TTGATGGGCAGCTTGGTTTC; the probe sequence was FAM-labeled CACGCCATGCGCTGCGG. GAPDH RNA was used as endogenous control and was amplified in the same reaction as NS5B (multiplex PCR) using primers and VIC-labeled probe recommended by the manufacturer (PE Applied Biosystem). The real-time RT-PCR reactions were run on ABI PRISM® 7900HT Sequence Detection System using the following program: 48′C for 30 min, 95′C for 10 min, 40 cycles of 95′C for 15 sec, 60′C for 1 min. The ΔCT values (CT_(5B)-CT_(GAPDH)) were plotted against the concentration of test compound and fitted to the sigmoid dose-response model using Graph Pad PRISM® software. EC₅₀ was defined as the concentration of inhibitor necessary to achieve ΔCT=1 over the projected baseline; EC₉₀ the concentration necessary to achieve ΔCT=3.2 over the baseline. Alternatively, to quantitate the absolute amount of replicon RNA, a standard curve was established by including serially diluted T7 transcripts of replicon RNA in the Taqman assay. All Taqman reagents were from PE Applied Biosystems. Such an assay procedure was described in detail in e.g. Malcolm et al., Antimicrobial Agents and Chemotherapy 50: 1013-1020 (2006).

Accordingly, the compounds of the invention are useful for treating viral diseases and disorders related to the activity of a virus, such as HCV polymerase.

Such uses as are described herein may be performed in a patient in need thereof, although in vitro and ex vivo uses, such as in diagnostic and research contexts, are also contemplated. References made herein to the use of compounds of the invention also refers to uses of compositions comprising compounds of the invention.

Examples of viral infections that can be treated or prevented using the present methods, include but are not limited to, hepatitis A infection, hepatitis B infection and hepatitis C infection.

In one embodiment, the viral infection is hepatitis C infection.

In one embodiment, the hepatitis C infection is acute hepatitis C. In another embodiment, the hepatitis C infection is chronic hepatitis C.

The compositions and combinations of the present invention can be useful for treating a patient suffering from infection related to any HCV genotype. HCV types and subtypes may differ in their antigenicity, level of viremia, severity of disease produced, and response to interferon therapy as described in Holland et al., Pathology, 30(2):192-195 (1998). The nomenclature set forth in Simmonds et al., J Gen Virol, 74 (Pt11):2391-2399 (1993) is widely used and classifies isolates into six major genotypes, 1 through 6, with two or more related subtypes, e.g., 1a, 1b. Additional genotypes 7-10 and 11 have been proposed, however the phylogenetic basis on which this classification is based has been questioned, and thus types 7, 8, 9 and 11 isolates have been reassigned as type 6, and type 10 isolates as type 3 (see Lamballerie et al, J Gen Virol, 78 (Pt1):45-51 (1997)). The major genotypes have been defined as having sequence similarities of between 55 and 72% (mean 64.5%), and subtypes within types as having 75%-86% similarity (mean 80%) when sequenced in the NS-5 region (see Simmonds et al., J Gen Virol, 75 (Pt 5):1053-1061 (1994)).
